ABSTRACT:
In a hammer mill or crusher for use in size reduction or even pulverizing rock, metals, or other materials, a rotating crusher and a contiguous surface are confined between opposing side walls and an inlet and discharge for the mill, with each side wall having supports designed for accommodating the arcuate formation of the crushing surface; a series of reversible grate bars span the distance between the side walls and associate at each end a structural shoe designed for stably positioning of each bar into the formed surface. Each grate bar and its end shoes are contoured on their sides to provide for their mating with adjacent bars and shoes when arranged into the crusher surface.
